The energy conservation 14 requirements adopted by the state building code commissioner 15 supersede and replace any minimum energy conservation 16 requirements adopted by a governmental subdivision. 17 The bill amends Code section 103A.8A to provide that all 18 single-family or two-family residential construction on or 19 after July 1, 2010, shall comply with the energy conservation 20 requirements, extending the requirements to existing residence 21 renovations and repairs. 22 The bill removes the language from Code section 103A.8A that 23 provides that the energy conservation requirements adopted 24 by the state building code commissioner are to supersede any 25 minimum requirements adopted by a governmental subdivision. 26 The bill makes conforming changes consistent with this 27 modification by striking Code section 103A.10(5). 28 The bill provides that if a governmental subdivision adopts 29 minimum energy conservation requirements that are not less 30 restrictive than the 2009 edition of the international energy 31 conservation code, then applicable residential construction 32 must comply with the energy conservation requirements 33 adopted by the governmental subdivision in lieu of the energy 34 conservation requirements adopted by the commissioner. 35 -2- LSB 2421SV (1) 87 gh/rn/nh 2/ 3
